I’m working on the hitch on my 641c I recently acquired. It’s using the remote cylinder setup to run an external hydraulic cylinder for lifting and dropping the 3 point. It has a bypass off of the hydraulic solenoid and I don’t know what it goes to. I do know with the valve closed I get power up and down. But with it open on the down stroke it just gravity’s down.
Anyone able to help me I’d what this is all about?
